Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece screening technology, and in particular to a decoction piece screening device for the production of traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to substances used for the prevention, treatment, and diagnosis of diseases, as well as for rehabilitation and health maintenance, under the guidance of TCM theory. TCM mainly originates from natural medicines and their processed products, including plant-based, animal-based, and mineral-based medicines, as well as some chemical and biological products. Among these, prepared TCM slices are one of the three pillars of the TCM industry. They are an essential traditional tool for TCM clinical diagnosis and treatment, and also an important raw material for prepared Chinese medicines. Their unique processing theories and methods embody the profound wisdom of ancient Chinese medicine. With the continuous improvement and maturation of their processing theories, they have become an important means of disease prevention and treatment in TCM clinical practice. There is no absolute boundary between raw medicinal materials and prepared TCM slices. Prepared TCM slices include some sliced ​​medicinal materials processed at the place of origin, whole medicinal materials, and slices that have been cut and processed. To improve the quality and grade of prepared TCM slices after production, screening and processing are necessary.

[0003] In the prior art, Chinese patent application number 202120711428.2 discloses a screening device for the production of traditional Chinese medicine decoction pieces, including a base plate. A screening device body is fixedly installed on the right side of the upper surface of the base plate, and a feed funnel is fixedly connected to the side of the screening device body away from the base plate. A protective cover is fixedly installed on the left side of the screening device body. This invention utilizes the cooperation between a separating sieve plate, a vibrating motor, a spring, and a movable block. The vibrating motor drives the separating sieve plate to shake, causing the mixture of traditional Chinese medicine decoction pieces inside the separating sieve plate to collide with each other under inertia. This effectively breaks up the mixture, solving the problem of the mixture clumping due to moisture caused by rainy weather. Breaking up the damp mixture prevents mold growth, reduces waste and loss of traditional Chinese medicine decoction pieces, and improves the pass rate of traditional Chinese medicine decoction pieces.

[0004] However, the above-mentioned technical solutions are time-consuming and labor-intensive because the separation sieve plate can only hold and screen a certain amount of Chinese herbal medicine pieces when screening them. After each screening, the Chinese herbal medicine pieces inside the separation sieve plate need to be removed before they can be put in again for screening. Moreover, the screening continuity of Chinese herbal medicine pieces is poor, which greatly reduces the screening efficiency. Therefore, we propose a Chinese herbal medicine piece screening device for the production of Chinese herbal medicine pieces to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during the screening of Chinese medicinal herbs, the separating sieve plate can only hold and screen a certain amount of herbs.

[0035] With the above structure, by starting two vibrating motors 15, the first sieve box 9 and the second sieve box 10 can be driven to vibrate. Here, the sieve holes on the first sieve box 9 are larger than the sieve holes on the second sieve box 10, so that the Chinese herbal medicine pieces can be initially screened through the first sieve box 9. After the initial screening, the Chinese herbal medicine pieces will be discharged from the box 1 through the discharge hole 12 on the left and collected. The Chinese herbal medicine pieces that are screened will fall onto the second sieve box 10 for secondary screening. Finally, the Chinese herbal medicine pieces that are screened will be discharged from the box 1 through the discharge hole 12 on the right and collected. Finally, the fine impurities that are screened through the second sieve box 10 will fall into the slag collection box 16 at the bottom of the box 1 for collection.

[0036] As a preferred embodiment of this utility model, discharge holes 12 are provided on the left and right inner walls of the box 1. The left end of the first sieve box 9 and the right end of the second sieve box 10 pass through the two discharge holes 12 respectively and are slidably connected to the inner wall of the discharge holes 12. By opening the discharge holes 12, it is convenient to discharge the screened Chinese herbal medicine pieces and to collect them.

[0037] As a preferred embodiment of this utility model, baffle plates 13 are welded to the bottom of both the first sieve box 9 and the second sieve box 10.
